Collagen is essentially the most considerable protein within the human physique and serves as a structural part in pores and skin, bones, tendons, ligaments, muscle tissues, and connective tissues. Also known as the physique’s “glue,” collagen offers stability, energy, and elasticity all through the physique. Nevertheless, pure collagen manufacturing begins to say no in our mid-20s, and this decline accelerates on account of components like solar publicity, smoking, and stress.
“After age 20, the dermis layer produces about 1% much less collagen annually, resulting in thinner, much less elastic pores and skin.”
— Harvard Well being Publishing
Because of this, supplementing with collagen has turn into a preferred technique to offset these age-related declines and enhance general pores and skin, joint, and hair well being.
Collagen dietary supplements sometimes come within the type of powders, capsules, or liquid pictures. Most are constructed from bovine (cow) or marine (fish) sources and are hydrolyzed into collagen peptides, that are smaller amino acid chains which might be simpler for the physique to soak up.
“Hydrolyzed collagen is damaged down into peptides, that are absorbed extra effectively within the gastrointestinal tract.”
— Journal of Scientific Vitamin
Many formulation are additionally fortified with vitamin C, hyaluronic acid, zinc, or biotin to spice up their effectiveness. These components work synergistically to help collagen synthesis, hydration, and tissue restore.
Collagen accounts for about 30% of the physique’s whole protein and as much as 75% of the dry weight of your pores and skin. It offers the tensile energy essential for pores and skin, ligaments, tendons, cartilage, and connective tissues.
There are 28 identified sorts of collagen, however varieties I, II, and III are essentially the most prevalent and clinically studied:

— Crowley et al., Worldwide Journal of Medical Sciences (2009)
“Every day collagen hydrolysate led to a major discount in joint discomfort in bodily lively people over 24 weeks.”
— Clark et al., Present Medical Analysis and Opinion (2008)
Collagen Absorption and Bioavailability
Hydrolyzed collagen peptides (2–10 kDa) are absorbed within the small gut and enter the bloodstream quickly. Key dipeptides like Professional-Hyp and Gly-Professional are bioactive and stimulate fibroblast exercise.
“Particular dipeptides from hydrolyzed collagen, significantly prolyl-hydroxyproline, stimulate fibroblast proliferation and hyaluronic acid synthesis in vitro.”
— Shigemura et al., Journal of Agricultural and Meals Chemistry (2011)
Closing Ideas
Collagen dietary supplements provide sturdy, research-supported advantages for:
-
Pores and skin hydration, elasticity, and anti-aging
-
